,lMPROVEMENT lN SLED OR SLEIGH RUNNERS.

Specification forming part of Letters Patent No. 35,106, dated April 29,1862.

To all whom it may concern.-

Be it known that I, S. H. NOBLE, of Vernon Springs, in the county ofHoward and State of Iowa, have invented a new and useful Improvement inthe construction of Sled or Sleigh Runners; and I do hereby declare thatthe following is a full, clear, and exact description of the same,reference being had to the accompanying drawings, making a part of thisspecification, in which Figure 1 is a side view of my invention; Fig. 2,a longitudinal central section of the same, taken in the line .r :r,Fig. 3; Fig. 3, a transverse vertical section of the same, taken in theline y y, Fig. 1.

Similar letters of reference indicate corresponding parts in the severalfigures.

This invention consists in constructing a sled or sleigh ru nu er ofcast metal and wood combined in such a manner that a straightpiece ofwood may be used for the main portion of the runner and cast metal forthe crook or curve and also for the shoe of the wood portion.

The object of the invention is to avoid the natural wood crook and thesteamed and bent crook of the ordinary wooden runners, and therebyobtain a much more durable as well as a more economical runner thanthose constructed entirely of wood, as usual.

To enable those skilled in the art to fully i understand and constructmy invention, 1

will proceed to describe it,

A represents the straight portion of the runner, which'may be of wood,of any suitable dimensions, and provided at its front end with a tenon,a, as shown clearly in Fig. 2.

B represents the front portion or crock of the runner, which is ofcast-iron, and is cast hollow or with a socket, b, to receive the tenon1 a of the wood part A of the runner.

The cast-iron part B may have its lower part, C, extend along the wholelength of the wooden part A of the runner to form a shoe, which may besecured to A by means of bolts or screws b, one or more, as shown inFig. 2.

The runner thus formed may be very cheaply constructed. The casting B ofcourse can be furnished at a very moderate expense, and a perfect crookobtained of any desired curve, and as no knees require to be attached toit, and it is not subjected to any great strain or stress, cast-ironwill answer a good purpose. The wooden part A has the knees attached toit in the usual way, and it is firmly retained in position at its frontpart in consequence of the tenon a fitting in the socket b. of the castmetal B.

The objection to the natural crook of the wooden runner is that it isliable to split and warp, and the steamed and bent crooks are liable toget out of shape, as they will bend or readily give if subjected toconcussion, and when once thus bent the metal shoe prevents them fromspringing back to their proper position, the shoe giving or yieldingwith the wood and holding the latter in misshaped form. Thesedifficulties are obviated by my invention, while a very durable andcheap runner is obtained, for the labor of putting the two partstogether is very trifling, and the wood part A, being perfectlystraight, maybe furnished at a small cost, and the labor of applyingspecial shoes, as heretofore, is dispensed with.

I would remark that if steel shoes should be required in certain casesthe crook B maybe cast without the shoe C, and a straight steel shoebolted to A, the front end of the steel shoe lapping over or under theback end of i the lower part of B.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent as a new and improved article of manufacture,is

A sled or sleigh runner formed of a castiron crook, B, with or withoutthe shoe 0, and a st 'aight wooden portion, A, combined or put together,substantially as herein shown and described.
